` -nuW-w IMPROVED MEAT-CHOPPER.

Th'eSeh-edule referred to in these Letters Patent and making part of l the same. V

I, ARTHUR Meerman, of salem, -in celumbiene county, and State of Ohio, have invented certain Improveniente in Meat-Mincing or ChoppingMachines, of which the following is a specification. The nature of my invention `relates to the combination of a pair of knives or cutters, with a rounded or bevel edge, `so mounted and operated that a verticalor npanddown motion is imparted, and, also, a

. rotary niotion upon a cent-ral axis, so timed as to turn,

say five to teu degrees, when the knives are raised out or above' the meat fora fresh out, thus, after successive cuts, to traverse around, 'making vthe entire revolution of the stationaryblock, with its choppingbed inclined at an angle, say, of five to ten degrees to the centre, (or somearceof a circle dished 4to or from the` circumference) by a `novelV arrangement of the mechanism, to produce the combined vertical and rotary motion on the central shaft to which the knives are affixed. t i;

jfFigure 1 is a perspective view of my machine. jilFigure 2,'a side.elevation, showing the knives in the cylindricalI hopper.

. Figure 3, an end elevation, to show the side gearing, 85e. e

Figure 4,- some of the mechanism detachedfrom lthe table or bed. e

Figure 5, the block and knives, with the cylindrical` hopper removed.

A is thebed or table, supported onthe legs l.

D `is a ring or sunken 4portion to receive the block B, which has a shouldered offset around the upper circumference for the `cylindrical hopper O, and-is also centrally perforated for a, 'tubular shaft, E, which is held by itshead. e, e and stationary, as is also the block B. e e

The shaft F, that sust-ainsethe knife-head N, passes through the `tube E, and rests upon a square step, M.

Thisstep has a projection on` both sides, to which the links P P 'areconnectcdfor a pivot.

Two similar links, P P, are also affixed on pivots to lugs p, beneath the `tableA, and jointly hinged togather centrally, and `held on pivot-bolts in the slotted ends q of vthe forked pieceQ, partly embracing the tubular shaft E on its back motion, and drawing the united link-pieces, I I" and P P, centrallyforward, and pushing them back, thereby shortening the distance between the xed points at p and r, both in a perpendicular line with the shaft E F, giving the step, with its appendages, `an np-and-down motion.

This is produced by connecting theforkcd piece Q on one side of an oblong slotted bar or guide-piece R. The parallel sides guide the sliding block. S with its flanged sides. l i 1 i `Through `this block S the crank T passes, the revolving motion of which carries the guide-piece back and forth horizontally.`

The jointed arms W X are also connected to the guide-piece R, and the upper end of X, held bya pivot in a lug, x, .centrally aflixed to the hind end of the table, underneath. l t

.A handle, a, to the cog-wheel U, meshes intoa pinion, V, having its bearings in brackets u.

The crank-shaft T is operated by the pinion V, and

operates the cogged wheel Uon the opposite side,A e

and a pinion, V', on the hub of a {1y-wheel, m, which is fastened by a .stud-pin, in order to give any desired amount of speed. By this arrangement of the gearing, great power is also gained thereby, in combination with the links fixed at two' points, so that when the resistance comes on the knives, the pressure is all upward on the links; j hence, by this peculiar motion, any amount of speed can be applied or given to the knives, gaining in power, also, by reducing the comparative size in the wheels for getting this motion or speed on the knives. i The vertical motion of the knife shaft, by means of the oscillating jointedlevers and guide-way and action of the crank, being understood, it remains to explain how the rotary motion to the knives is imparted. To the step-M, (that supports the shaft Ii-, which has a cogged wheel, G, fixed to it,) are side brackets, b, for the fbearings of a screw-pinion, H, which meshes intofthe cogged or toothed wheel G ou the shaft-F. The ratchet-wheel I, with its pawls J K, revolves the screw-wheel or pinion intermittently by the intervention of a vibrating arm, z, to which one of the pawls J is connected. (The other pawl,l K, is attached to the step M.) A rod, Y, fastened above, under the bed or table A, is connected `by a pivot-bolt to the arm z, which operates on the shaft that supports the worm H. By moving thiserod Y further out on the arm z, less motion is given to the knives, and is a means of regulating them to cut coarser or finer, and constitutes an adjustable feed andintermittent revolving motion, Without interfering with the up-aud-down motion, whichgivesl four cuts to each frevolution of the'crank. t

The bevel or rounded dish of the block, and lance or shear-shape of thecutt-ing-edge of the knives k, attached. to their supporting-head N, to the top of the shaft F, which has a screwend for the binding-nut o, is also a novel feature. t

The action of the knives, I deem important and new. The manner of imparting a more or less rotary motion intermittently, just when the knives are raised up out of the meat, the link motion, t and gearing of the crank 'and fly-wheel, have new and valuable features.

I am aware that knives vibrating up and down, for mincing meat, by means of a crank-shaft, in combination with a circular revolving tub or block, have been used before. -I, therefore, do not claim the reciprocating vertical knife-shaft, operated by a crank and central guide tube, combined with a. toot-hed lim and arms W X, and guide-WWB', operated bythe crankloose pinion, for snob I do not use. shaft T and sliding block S, the arrangement of the What', I claim, ns my invention, isgearing U U X, o fu', in connection with the fly-wheel 1.
